I don't think we're close to using something like that in combat operations (maybe 15 years?) however, for many applications that would be great in rear echlon areas. I can think of a million uses for something like that in loading trucks, setting up camps off loading cargo ect. Were something took 15 to 20 troops to accomplish before now would take 3-5.
Just a couple of troops could offload an entire convoy without the use of a forklift (think logistics) in a shorter time with less use of manpower and materials.
Of course a smaller man portable version would have endless applications to combat operations when it comes to hauling gear or kicking in doors. Car blocking a road.....no problem!
